The nutritional quality of the protein in the leaves of 11 Asphodeline (Liliaceae) species was investigated by the determination of the amino acid composition and calculation of several nutritional parameters. The average protein content was 4.7% and ranged from 2.5% in Asphodeline damascena ssp. rugosa to 8.2% in A. turcica. The most abundant essential amino acids were Thr (5.7%), Val (6.0%), Ile (4.7%), and Trp (2.1%). The amino acid composition of Asphodeline peshmeniana was well equilibrated according to Food and Agriculture Organisation standards, but Lys and sulphur amino acids were at limiting concentrations in all the other taxa. Determination of the protein efficiency ratio and biological value revealed that the protein in the leaves of Asphodeline species is of high nutritional quality. Hence, the Asphodeline leaves that are typically used in Turkey for the preparation of salads, represent a good source of protein with high levels of several essential amino acids and a good nutritional value. Analysis of the similarity based on the amino acid composition indicated the existence of different clusters that are consistent with the taxonomical classification, area of distribution, and morphological similarities of the Asphodeline species.
通过测定氨基酸组成和计算几个营养参数，研究了 11 种孤挺花科（百合科）植物叶片中的蛋白质的营养质量。蛋白质含量的平均值为 4.7%，范围从 2.5%的 Asphodeline damascena ssp. rugosa 到 8.2%的 A. turcica。最丰富的必需氨基酸是 Thr（5.7%）、Val（6.0%）、Ile（4.7%）和 Trp（2.1%）。根据粮农组织标准，Asphodeline peshmeniana 的氨基酸组成均衡，但在所有其他分类群中 Lys 和含硫氨基酸的浓度都有限制。蛋白质效率比和生物价值的测定表明，孤挺花科植物叶片中的蛋白质具有较高的营养质量。因此，在土耳其，通常用于制作沙拉的孤挺花叶片是一种优质蛋白质来源，含有多种必需氨基酸和较高的营养价值。基于氨基酸组成的相似性分析表明，存在不同的聚类，与孤挺花科植物的分类学分类、分布区域和形态相似性一致。
